Hello dear Understand your concern. Mucus discharge is normal during pregnancy. But It should be clear,milky, odorless and slippery in nature. It is abnormal if there is change in color, consistency, odor along with itchiness and irritation. Most common cause in your case may be yeast infection (Candidiasis) or chlymadia. Of course azitral is safe during pregnancy. No worry. In addition you can take clotrimazole cream or suppository for faster relief. In addition to drugs, take the following advice Wear loose, cotton underwear Bathe or shower frequently Wash vagina with warm and salt water after urination to maintain hygiene Change out of sweaty or wet clothing as soon as possible Do use hygiene sprays add yogurt and other fermented foods to your diet to promote healthy bacteria Reduce the amount of sugar you eat.
